Large Format, Passageway & Container Bellows

Dynatect manufactures customized bellows for connecting mobile buildings, ISO or intermodal containers, walkways, or modular spaces. Some applications where flexible passageways may be needed to connect modular builds include classrooms, offices, training facilities, oil & gas camps, disaster relief, hospitals, hospitality rooms. Beyond container bellows, Dynatect has fabricated large connecting bellows for other applications including ferry loading bridge, airplane loading gangways, and vehicle connections. Dynatect will work with you to design and manufacture passageway bellows for your application and ship anywhere in the USA or the world.

Benefits

Efficiency: Mobile building bellows result in fewer external doors
Safety: Protects occupants from rain, heat, wind, snow and stairs when transitioning between spaces
Energy Costs: Reduces losses in temperature- and humidity-controlled rooms
Cleanliness: Limits external environmental contaminants (surgical, food prep, electronics)
Acoustics: Minimizes exposure to outside noise and frequency of door operations (construction, high traffic)
Asset Reuse: Connects to existing structures with custom mounting designs and are reusable

Features

Construction: Made from a strong, lightweight aluminum reinforced structure with durable CSM coated fabric
- Translucent fabric available to allow ambient light
- Structural floors available
Adaptability: Bellows adjust to typical multi-axis misalignment of modular spaces
Integrity: Reinforced for environmental loading including rain/wind/snow
Durability: Capable of handling varying temperatures from -30˚F to 130˚F, and UV resistant
Customization: Variable cross sections, lengths, and mounting designs available. The bellows is customized and manufactured to your specific parameters and mounting requirements.
Portability: Engineered for compressed shipment, fast installation, and reusability

Experience

Dynatect has over 80 years of experience in designing and manufacturing covers to protect equipment and enhance safety.

Covers have been designed for use in any industry where a dynamic and flexible cover is needed to conceal and protect, without interfering with the equipment’s intended motion. Dynatect’s bellows assemblies are customized and manufactured to your specific parameters and mounting requirements.

Our Container/Building Bellows are flexible connecting bellows that link modular structures such as shipping containers, mobile offices, and emergency shelters. These bellows create enclosed walkways that improve environmental control, privacy, and sanitation. Check out our Shipping Container Bellows page for more!

Large Format Bellows Applications

Dynatect has provided large, customized bellows for a variety of applications such as:

Camper truck cab – pass-through bellows
Enclosures for sealing off equipment test processes
Bellows for large machines, where heat and pressure are present
Large-scale roof bellows for machines (aka “machine roof covers”)
Large duct bellows for connecting larger fixtures with irregular movement
Clamshell-style bellows to protect a large optical instrument from adverse weather conditions

Dynatect designed a custom pass-through bellows to connect a truck cab to a camper body, accommodating a high angular offset for flexible movement. Bellows material: CSM-coated fabric. Overall size: 41x35x4.5 inches.

Large-Format-Bellows-Testing-Enclosure-1440

These record-breaking bellows, made from clear, reinforced vinyl provided a complete seal for a 20 ft. long x 15 ft. wide by 30 ft. high enclosure for equipment testing.

Large, Reinforced Bellows: This application required a bellows capable of withstanding cyclical pressure. Dynatect provided a modified Gorframe bellows, reinforced with wires for a predictable travel path, maintaining its form under pressure. This design offers a favorable extended-to-retracted ratio and long service life. The bellows is utilized in a high-impact velocity quench, a metal processing heat transfer process.

Dynatect designed a customized bellows system to accommodate high shear stress and ensure durability in electronics recycling machines. Bellows folds with extra material were incorporated to handle the significant shear movement, also requiring extra heavy-duty fabric to withstand the increased strain.

This large 76-section Heat-Sealed bellows cover incorporates specific reinforcement patterns and materials to ensure durability and performance in its intended application. Dimensions: ~106" wide, 20" retracted, ~200" extended. The stiffener profile is optimized for weight reduction. Aluminum binding throughout reinforces shape.

Dynatect created a set of bellows with a clamshell opening design, that together span 12 feet. Its primary purpose is to create a protective seal around an optical instrument, shielding it from adverse weather conditions. The material used is a special vinyl that is resistant to water, mildew, and ultraviolet rays. Aluminum support ribs provided strong but lightweight support and structure, and were strategically placed to minimize the retracted dimension / compressed size of the cover.
